Manufacturing method for color filter substrate and manufacturing method for liquid crystal panel

A manufacturing method for color filter substrate is disclosed. The method includes: coating and exposing three layers of photoresist materials on a first substrate, and colors of the three layers of the photoresist materials are respectively a red color, a green color and a blue color; in the coating and exposure processes, a red color resist block, a green color resist block and a blue color resist block are formed; forming a light-shielding layer through mixing of two different colors of the photoresist materials in the three layers of the photoresist materials; and forming a spacing layer through stacking of two different colors of the photoresist materials in the three layers of the photoresist materials. A manufacturing method for liquid crystal panel is also disclosed. The present can simplify the manufacturing process of the color filter substrate, reduce the process of the liquid crystal panel and decrease the manufacturing cost.
